ANALYSIS AND IMPLEMENTATION OF D-SSVR FOR LOAD FLOW SOLUTION IN RADIAL DISTRIBUTION SYSTEMS

In this paper, optimal location of Static Series Voltage Regulator (SSVR),a member of D-FACTS devices family, for voltage improvement and loss reduction in distribution system, is implemented. A simple and modified method for node and line identification used in load flow calculations for solving radial distribution network is presented. In order to minimize line losses of power systems, it is crucially important to define the location of SSVR to be placed in the given distribution system. D-SSVR is a distribution static Series voltage regulator, which corrects the voltage magnitude at the load end irrespective of voltage disturbances at the source. The proposed method is successfully applied to the IEEE-15 bus and IEEE-29 bus distribution systems.
